BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parameter control method for a cordless telephone second generation (CT2) terminal with a built-in wireless pager. In particular, an operator of a network management system needs to be able to When a predetermined parameter is required among the parameters, the present invention relates to a parameter control method for a built-in wireless pager-type CT2 terminal which can be easily changed via wireless.

Conventional Technology and Its Problems

Recently, with the continuous development of the paging network and pager related technologies, the wireless calling service and the CT2 service have emerged as the service area has been expanded and the call reception rate has been improved.

The wireless calling service is a reception-only service that delivers call signals and messages to subscribers using a public switched telephone network (PSTN) and a wireless calling network, and the CT2 service is an advancement of the analog home wireless telephone (CT1). It is a popular service using pedestrian-oriented small, low-power terminals that can communicate outdoors.

In addition, the public CT2 service is a mobile phone service exclusively for outgoing calls.The base station is installed on the wall or on the roof of a building where frequent people come and go, such as stations, malls, airports, bus terminals, and streets. It is a service that can be called by anyone who is a terminal subscriber, and business and home use mainly install a base station in a building.

It is pointed out that the CT2 can only make outgoing calls, and various complementary methods (that is, a method of adding a call function through a built-in Meet-Me service or manual and automatic location registration, etc.) are devised. have.

In the above, the first Meet-Me service means that if a caller makes a call to the CT2 system and waits without hanging up the call, the CT2 subscriber is notified of the connection waiting state by using a wireless call and is waiting for a call to the CT2 system. Speak service to caller.

The second incoming call by manual location registration refers to a service that registers a location with a base station when the CT2 terminal subscriber wants to press the terminal keypad to make a call without leaving the base station.

The third incoming call by automatic location registration refers to a service that allows a subscriber to register a location at a predetermined time interval or register a location on a CT2 terminal even if the subscriber does not manually register a location, and automatically tracks the terminal.

As described above, the CT2 has been developed from the outgoing call-only service to the state where the incoming service is now possible. In the future, CT2 has become a universal service for personal mobile communication by applying improved location registration, handover, and roaming service. It seems to evolve.

In addition, the wireless communication service is expected to be able to provide more enhanced service in the form of a communication network.

In particular, the combination of the pager capable of incoming service and the CT2 capable of originating service will lead to the expansion of the range of service provision through complementation, and through this, the location of the lost location tracking service and the bus movement location indication service. It is expected to create various additional value-added services that can create additional new services such as tracking service and stolen vehicle, and overcome the unidirectionality of wireless calling and CT2.

The above described CT2 basic functions are possible through CT2 / CAI.

However, in the case of the parameter change related to the radio call or the function set as required by the service provider, the subscriber carries the CT2 terminal with the pager directly and visits the service center or the network management center to provide the parameter change service. There was a problem that must be received.

[Problem to Solve Invention]

The present invention provides a method for changing parameters not supported by CT2 / CAI. When a user or operator needs to change a predetermined parameter in a subscriber's terminal (i.e., a specific subscriber, multiple subscribers, or all subscribers), the operator may change the network management system. The purpose of the present invention is to provide a parameter control method that can easily change a specific parameter of a wireless pager built-in CT2 terminal by using a wireless device.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a method of controlling a wireless call information transmitted from a wireless call system by a pager in a CT2 terminal, and a control command requesting a change of a predetermined parameter in the received wireless call information. Determining whether or not is included, and if there is no control command requesting a change to a predetermined parameter, processing is performed as general radio call data, and if a control command is detected, the control area is determined to identify a specific inside the CT2 terminal. Changing the data of the control area copy, and if the parameter change in the CT2 terminal is completed above, check whether the response reply field is included in the response command field in the control command, and if there is no response request signal, the process is terminated. When requested signal, the desired parameter is automatically dialed. It can be achieved by forming a response signal indicating the changes have completed a step of transmitting to the base station.

Message transmission based on the distinction between individual, group, and all subscribers is made by the classification of CAP code, individual cap code for each subscriber, group cap code commonly assigned to terminals corresponding to the group, The message is distinguished and changed by cap codes that can be given to all terminals jointly.

Therefore, when it is determined that the operator needs to change a parameter in a specific subscriber's terminal, the subscriber within the terminal is automatically changed when a desired parameter change signal is transmitted from the remote network management system to the corresponding terminal over the air. You do not have to take any action to change the parameters.

If not, the process is processed as general radio call data, and if a control command is detected, the control step is transmitted to the CT2 terminal unit 30 (S12), the step of determining the service control area from the received control command (S21), and Changing the setting value of the service area (S22) and detecting whether there is a response request in the reply status field in the control command word, and if there is a response signal through automatic dialing. CT2 is transmitted to the base station (5), and if there is no response request, characterized in that the step consisting of the step of changing the setting value of the corresponding service area (S23).

In addition, Figure 4 shows the format of the control command used in the method of the present invention, the control command area contains information indicating whether there is a service control area determination command and a response request, the data area of the changed parameter data The contents are included.

Referring to the effects of the present invention as follows.

First, the network management system (1) that performs remote control of network operations such as normal initialization, alarm, maintenance, software downloading, check of all equipment, and centralized management of services such as user database, authentication, billing, statistics, etc. For example, a specific subscriber can be called through a public switched telephone network (PSTN) to change the parameters for his CT2 terminal 4, or he / she can determine the specific subscriber by itself during the operation of the system. If it is necessary to change a parameter for the terminals of multiple or all subscribers, including the terminal of, the command to change the parameter is transmitted to the paging switch 2, and the paging switch 2 sends this command. The signal is converted into a radio call signal and transmitted to a plurality of radio call base stations 3 through a radio call network.

In addition, the radio call base stations 3 transmit the above-mentioned information wirelessly to the CT2 terminals 5 incorporating a radio subscriber of a specific subscriber and a plurality of or all subscribers.

Accordingly, the wireless calling unit 20 in the CT2 terminal 4 receives the wireless calling signal transmitted from the wireless calling base station 3, determines whether it is a control command, and if so, the CT2 terminal unit ( 30), otherwise it is treated as general radio call data.

If the command transmitted from the wireless caller 20 is a change command for a predetermined parameter among the several parameters in the CT2 terminal 4, the CT2 terminal unit 30 in the CT2 terminal 4 determines the service control area. When the set value of the corresponding area is changed, and the reply field in the command requests the response signal, the response signal indicating completion is transmitted to the CT2 base station 5 through the automatic dialing method.

Therefore, the CT2 base station 5 transmits the parameter change response signal transmitted wirelessly from the CT2 terminal 4 to the CT2 base station control device 6, so that the CT2 base station control device 6 This change response signal is transmitted to the network management system 1 via the PSTN, so that the network management system 1 can know at a remote location whether a specific parameter in the CT2 terminal 4 desired by the user has been changed correctly.

At this time, since the telephone dialing is used between the CT2 base station controller 6 and the network management system 1, it is transmitted to the public switched telephone network (PSTN), not the network (PSDN) using X.25, and the network management system (1). ) And the paging switch 2 are interfaced with a data line.

The operation of changing a predetermined parameter in the CT2 terminal 4 with the built-in wireless pager will be described with reference to the flowchart of FIG. 3.

First, in step S11, the wireless call unit 20 embedded in the CT2 terminal 4 receives the wireless call signal transmitted from the wireless call system, and checks whether the wireless call information received in step S12 is a control command. If it is not a control command, the process is terminated after processing as general wireless call data, and if the command is required to change a predetermined parameter, the command is transmitted to the CT2 terminal unit 30.

In step S21, it is determined which service control area the change request data for the predetermined parameter is for changing, and in step S22 the setting value of the area is changed.

In step S23, it is checked whether there is a request for a reply in the reply field in the control command. If so, the CT2 terminal 4 completes a change to a predetermined parameter and then sends a response signal indicating the response to the CT2 base station 5; And report to the network management system 1 via the CT2 base station controller 6.

That is, the CT2 terminal 4 requests a link to the CT2 base station 5 through the automatic dialing method after the change of the predetermined parameter is completed, and the CT2 base station 5 sends this request to the CT2 base station controller 6. After reporting to the network management system 1 through the link to the CT2 terminal 4 to form a link, the completion signal is reported to the network management system 1 for a change to a predetermined parameter sent from the CT2 terminal 4. Will be.

Of course, the parameter change command processing part and the response signal generated in the CT2 terminal 4 relate to a part outside the range of the parameter change area used in the CT2 / CAI protocol. Follow the protocol criteria.

[Effects of the Invention]

As described above, according to the present invention, when a subscriber requests a change of a predetermined parameter through a telephone or the like or has a request of an operator of a network management system, a change is required for a predetermined parameter in one or more subscriber stations. Operators can easily make changes at any time over the air using a network management system without having to call each terminal subscriber.

Therefore, it is possible to completely eliminate the inconvenience of subscribers and operators due to the change of parameters is expected to enhance user convenience.
